Back to Basics Hammer Milling and Jet Milling Fundamentals

instability, explosibility, toxicity, particle size and particle-size distribution, flowability, and bulk density. Hardness/softness. The Mohs scale of mineral hardness is frequently used to specify hardness. A hammer mill is typically good for grinding softer materials with Mohs hard-ness ranging from 1 to 5, while a jet mill can grind materials

How is Finished Particle Size Determined? Schutte

08/08/2013  In the majority of hammer mill applications, the key factor determining finished particle size is the the screen. Any material that enters the grinding chamber must be reduced to a size small enough to pass through the screen that covers the mill’s discharge opening. Because of this the screen size provides 70% of the control over the finished particle size. Size reduction takes place when ...

Hammermill tip speed adjustment alters particle size ...

An alternative solution to reducing particle size is to adjust the hammer tip speed. This could potentially allow different particle sizes to be obtained from a single screen hole diameter, eliminating or reducing the need for screen changes. Because tip speed is a function of hammermill diameter and motor speed, it is necessary to have a variable frequency drive on the hammermill motor to ...
